high; July to September. "Apparently not the same as the plantof the coast of New England, 

 referred to this species, though nearly allied to it. Both exhibit a more or less manifest 

 involucre. " — Gray. 



Cymopterus? littoralis, (n. sp. :) "Low, subcaulescent; petioles elongate, dilated, and 

 sheathing at the base, above with the peduncles and rays tomentose-villous; leaves coriaceous, 

 deeply 3-lobed or more commonly trisected; the divisions roundish, callose-serrulate, often 

 3-lobed or 3-parted, densely tomentose beneath, glabrous and finelj^ reticulated above, the 

 veinlets impressed; umbels shorter than the leaves; leaflets of the involucre and iuvolucel 

 subulate, the latter equalling the glomerate (whitish) flowei-s; calyx-teeth short and subulate; 

 wings of the fruit equal (broad and white.) "On the sands of the sea-shore at Shoalwater 

 bay, scarcely rising above the surface, where its leaves lay prostrate. These are dark green 

 and glabrous, and nearly white below, drying up, but not deciduous; flowers gray and white; 

 ripe fruit, white." — Dr. Cooper. Root thick, petioles stout, a span long. Leaflets and 

 divisions of the leaf 1 or 2 inches long; peduncle 1 to 2 inches long; rays 10 to 12, half an 

 inch to an inch in length ; nmbellets capitate, many-flowered. The very little fruit gathered 

 is imperfect, but accords with that of Cymopterus, (except that the vittaj were not made out,) 

 but the foliage is widely diflerent from that of any species before known." — Gray. 



Peucedanum leiocarpum, Nutt. (G.) Prairies generally; on sandy sea-shore varies with 

 leaves broader and shorter; stem coarse, 1 to 2 feet; June. "The green stems are peeled and 

 eaten." (G.) 



P. fcenicdlaceum, Nutt. (T.) Prairies about Puget Sound; March 15 to June — ; common; 

 flowering when two inches high to one foot. "Root boiled and eaten." (G.) 

 Heracledm lanatum, Michx. (G.) Abundant on sandy prairies along coast; May. 

 Daucus pusillus, Mich. (G.) Rare on sandy prairie near mouth of Columbia; July. (Steila- 

 coom, S.) 



Glycosma occidentalis, Nutt. (T.) Common on rich prairies in shade; June to August. 

 CoNiUM MACCLATOM, Linn. "Large form of the northwest coast." (T.) Abundant every- 

 where in wet grounds, the large variety mostly near the sea, 8 feet high; June to October. 



EcHiNOPANAX horridom. Smith, (G.) Common in springy woods, from the highest parts of 

 the Cascade mountains to the coast; May 15. (Steilacoom, S.) 



CoRNUS Drummondii, (G. a. Meyer,) C. sericea, var? Torr. & Gray. Abounds along the 

 edge of rivers, in sandy soils, down to tide-water. I think this is distinct from the following, 

 though my specimens are too incomplete to decide from. 



C. PUBESCENS, Nutt. (T.) Not very common, in damp woods, Steilacoom; May 28; 15-20 

 feet high. Bark greenish, twigs dark purple, leaves from two to four inches long, one to two 

 and a half wide, ovate, obtuse or mucronate, glabrous, petals white. 



0. NuTTALLii, Aud. (G.) Common in the fir forests, about as far north as Steilacoom; May 

 1. Very similar to C. Florida, and about twice as large in all parts. Much more ornamental 

 in flower. 



C. Canadensis, Linn. Cascade mountains, 4,000 feet to the mouth of Columbia ; May. 

 LiNNEA BOREALis, Gronovius. (G.) Common in the same situations as Cornvs Caimdensis; 

 June. (Steilacoom, S.) 



Symphoricarpus racemosus, Mich. (G.) Common along river banks down to tide-water; 

 June. (Steilacoom, S.)
